Hello Ambika,

Please carefully review the ‘Update Name’ or ‘Update Connector’ steps. Ensure that any names you provide use only alphanumeric characters and underscores (e.g., use my_custom_name instead of my-custom-name).
If you are not prompted to rename anything, or if following these naming conventions still results in the same error, the issue is likely embedded in the marketplace template itself.

Yes, Connector name is in correct formate
